Filter fits just like stock and has worked great since I installed it. Once again, another great product from K&N.

The 'nut' on the bottom of the filter which is used for tightening the filter has sloped faces rather than vertical. This makes it more likely to 'rounding' when trying to torque the filter from locations perpendicular to its axis.

Anyone will agree that changing the oil filter on a Chevrolet Trailblazer is somewhat difficult and can be infuriating. With this filter, there is no need for a fancy tool. All you need is a socket and an extension. I will only be purchasing K&N Oil Filters from now on. Thank you for making a quality and practical product.

This is the best oil filter for the money...PERIOD!

These filters are the best, period. The nut on bottom is an awesome way to remove in a tight area. No need for oil filter wrench any longer.
